Constructor Detail

• Byte

  public Byte(byte value)

  Constructs a new Byte with the specified primitive byte value.

  Parameters:

  value - the primitive byte value to store in the new instance.

Method Detail

• toString

  public String toString()

  Converts this byte into its decimal string representation. The returned string is a concatenation of a minus sign if the number is negative and characters from '0' to '9'.

  Overrides:

  toString in class Object

  Returns:

  the decimal string representation of value.

• byteValue

  public byte byteValue()

  Gets the primitive value of this byte.

  Returns:

  this object's primitive value.

• equals

  public boolean equals(Object object)

  Compares this object with the specified object and indicates if they are equal. In order to be equal, object must be an instance of Byte and have the same byte value as this object.

  Overrides:

  equals in class Object

  Parameters:

  object - the object to compare this byte with.

  Returns:

  true if the specified object is equal to this Byte; false otherwise.

  See Also:

  Object.hashCode()

• hashCode

  public int hashCode()

  Returns an integer hash code for this byte.

  Overrides:

  hashCode in class Object

  Returns:

  this object's hash code.

  See Also:

  Object.equals(java.lang.Object)

• parseByte

  public static byte parseByte(String string)
                        throws NumberFormatException

  Parses the specified string as a signed decimal byte value. The ASCII character - ('-') is recognized as the minus sign.

  Parameters:

  string - the string representation of a single byte value.

  Returns:

  the primitive byte value represented by string.

  Throws:

  NumberFormatException - if string is null, has a length of zero or can not be parsed as a byte value.

• parseByte

  public static byte parseByte(String string,
               int radix)
                        throws NumberFormatException

  Parses the specified string as a signed byte value using the specified radix. The ASCII character - ('-') is recognized as the minus sign.

  Parameters:

  string - the string representation of a single byte value.

  radix - the radix to use when parsing.

  Returns:

  the primitive byte value represented by string using radix.

  Throws:

  NumberFormatException - if string is null or has a length of zero, radix < Character.MIN_RADIX, radix > Character.MAX_RADIX, or if string can not be parsed as a byte value.

• valueOf

  public static Byte valueOf(byte b)

  Returns a Byte instance for the specified byte value.

  If it is not necessary to get a new Byte instance, it is recommended to use this method instead of the constructor, since it maintains a cache of instances which may result in better performance.

  Parameters:

  b - the byte value to store in the instance.

  Returns:

  a Byte instance containing b.
